Detailed Product Overview
Phthalic Anhydride, with the chemical formula C8H4O3 and a molecular weight of 148.12 g/mol, is a white crystalline solid that plays a vital role as an intermediate in the chemical industry. It is primarily produced through the catalytic oxidation of ortho-xylene, a process that ensures a high degree of purity and consistency. This compound is highly reactive, particularly in forming esters and anhydrides, making it indispensable in the synthesis of various high-performance materials. Its solid state and chemical behavior enable it to effectively interact with other compounds, enhancing the properties of polymers and coatings in which it is used. In industrial applications, Phthalic Anhydride is crucial in the production of polyester resins, plasticizers, dyes, and pigments. It serves as a precursor to phthalate esters, which are essential in creating flexible and durable plastics. Additionally, it is integral to the formulation of alkyd resins used in coatings and adhesives, offering enhanced durability and resistance to environmental factors such as moisture and UV light. In the dye and pigment industry, Phthalic Anhydride contributes to the vibrancy and stability of colors, making it a key component in producing high-quality industrial products that require consistent performance and aesthetic appeal. The industrial grade of Phthalic Anhydride is tailored for manufacturing applications, ensuring it meets rigorous quality standards. Buyers should verify the consistency of its white crystalline appearance upon receipt, as this is a direct indicator of purity and quality. It is essential to cross-check the product's EC Number 201-607-5 and CAS Number 85-44-9 with the accompanying documentation to confirm authenticity and compliance with industry specifications. Ensuring these parameters are met is crucial for achieving optimal performance in its intended applications, as any deviation could impact the efficacy of the end products. Proper handling and storage of Phthalic Anhydride are critical due to its reactive nature. It should be stored in a cool, dry environment, away from moisture and direct sunlight, to prevent degradation and maintain its chemical integrity. The product is supplied in 25 kg polypropylene bags, providing adequate protection against contamination and moisture ingress during transportation and storage. When handling, appropriate personal protective equipment is necessary to avoid exposure to the compound. Kivi Industrial Chemicals Limited ensures that Phthalic Anhydride is packaged and transported under optimal conditions, maintaining its quality from supply to application, which is particularly relevant in the East African industrial context.
